Chemistry (mol)

How many mol of NaHCO3 are in a 454 g box of baking soda (NaHCO3)?

A. 3.81 x 10^4 mol NaHCO3
B. 1.85 x 10^–1 mol NaHCO3
C. 5.40 x 10^0 mol NaHCO3
D. 6.33 x 10^–20 mol NaHCO3

I tried doing the calculations and a came the closest but it wasn't exact...

  1. Na = 23 g/mol
    H = 1
    C=12
    O3 = 3*16 = 48
    sum = 84 grams / mol

    454 g * 1 mol/84 grams = 5.40
    by the way luckily 10^0 = 1 :)
